The entire reason they went to eng 1 over APU is because guys put it on as soon as they land and run it the entire taxi to include waiting for rampers or a gate to open. Or they run it and get up and leave with it running for hours. Put it on when marshallers are in position and cut it when either you get ground air or 2/3 of the pax are off. Those of us in row 30 thank you.

Before push use it if you need water pressure or it gets warm or 10 prior whatever occurs first.

they don’t care about cycles. It’s about irresponsible usage. This is not hard. Don’t make us sweat and don’t run it for hours
